Temporal Predator and Phantom Ghost (OCs X RWBY Vol4+)

Nightmare

Now in the Chaos that is Haven Academy, the main room was filled with gunfire and the clash of weapons. Ruby vaulted over a Darkhunter, using Crescent Rose to defend herself from a swing of his double hatchets. His jade green mistralian cloak flung around with every movement he made. She fired at him, before his eyes flickered light green as a platform of Aura redirected the shot towards Ren, who dodged it, causing the shot to bounce off of Hazel.

Yeta rolled to the side as lightning struck where he once stood. A woman with long, orange hair, her outfit a feathery black dress that had a heart-shaped window to her chest, was playing an electric guitar, which sparked with purple lightning, the same kind that attempted to hit him.
The white-eyed warrior teleported backwards, dodging a barrage of gunfire from some kind of automatic weapon.
It was hard to keep up with all the chaos.

Ghost did multiple backwards cartwheels to dodge the flurry of swings from the sickle on a chain his attacker swung at him with.
"Enzo, your left!" A Darkhunter with a southern accent called out to the middle-eastern looking Darkhunter attacking Ghost. Instead of dodging, Enzo shoulder tackled the approaching Jaune, sending his entire body weight against his charging shield, knocking over the blonde.

Ghost defended his apprentice by drop kicking Enzo in the face, sending him out of sight, before Ghost was forced to throw his forearm up to block a swing from a large steel baseball bat. Ghost’s aura flared into the veins of his arm, creating a dim glow as the weapon bounced off his arm like a steel wall. Ghost smirked as he noticed this, before taking the Wing Chun stance.
"Joey, not point blank!" Another Darkhunter yelled out as the brown-haired Darkhunter hit Ren in the side, his distraction with the bat-wielding Joey allowing Nora to slam her hammer into his side, sending him screaming in pain as he was flung off.

Swords made of Aura came from the flung Darkhunter, firing everywhere and forcing a few to dodge or block. An explosion rang through the room as Ruby was locked in a 3v1 against three Darkhunters. She had never swung her scythe so fast, having to keep up this fight while dodging gunfire, railgun shots, and-
Ruby slid under a Rocket, which exploded behind her and sent her forwards, crashing her into one of the Darkhunters. She uprighted herself and sidestepped a stab from another. She managed to land a good right cross on the one she ran into, who swung at her with a pair of switchblades.
However, Yeta appeared next to her and grabbed the spear a Darkhunter was wielding, hitting him in the jaw with the blunt end, then twirling it and blocking the switchblades. He then proceeded to lay the beat down on the three Darkhunters using just the staff, twirling it and jabbing with no time for the three to breathe, allowing Ruby to get away, until Yang appeared and held the unarmed Darkhunter in a chokehold, before getting kicked away by Mercury.

Joey's bat turned into some kind of automatic rifle as he started firing at Ghost point blank. However, with his new defense still up, every single round ricocheted off his forearm and all around the room.
Then, Ghost's aura glowed at a peak. Ghost's grin grew psychotic as he was about to royal release all this energy upon this poor Darkhunter-
Then the same bastard who got the drop on Yeta and him slid in, knocking Joey aside, and in a single swing of his blade, he shattered Ghost's defenses and sent our warrior flying.

"What a wonderful sight, seeing that shithead getting exactly what he deserves!" Runt sneered as he watched the green blur fly by.
Cinder removed the strange crystal from her glove, then slid it into some strange cylinder container. Runt's phantom vanished, and Cinder threw the container onto the ground, shattering it.

"In the brightest light, You shall make it night.
Rise, and make this dream turn to Nightmare."
Cinder recited, and the cylinder began to bubble and expand. Grimm bone platings emerged from the cylinder as the mass got larger and larger.
